The crank arm 30 includes a first arm 30a and a second arm 30b coupled to each other with an elastic member interposed between the first arm 30a and the second arm 30 b. The crank arm 30 after being folded and stored can be unfolded outward by the elastic force of the elastic member. More specifically, the crank arm 30 is always subjected to an outward-spreading elastic force under the action of the elastic member; therefore, after the crank arm 30 in the technical scheme is folded, the storage state can be kept in the storage space through the buckle assembly, and the fixing function of the buckle assembly can overcome the restoring elasticity of the elastic piece.

In the actual use process, a user pushes the front edge 101 inwards to drive the crank arm 30 to fold inwards, and the front edge 101 or the crank arm 30 keeps a stable storage state through the buckle assembly after being folded completely; when the crank arm 30 needs to be unfolded, the buckle assembly is released, and the crank arm 30 is unfolded outwards under the restoring elasticity of the elastic piece, so that the front edge 101 is further pushed to be unfolded outwards. The folding or unfolding of the crank arm 30 is realized under the cooperation of the elastic member and the buckle assembly.

In addition, when the crank arm 30 needs to be stored, the user lifts the front edge 101 and folds the crank arm 30 inwards, and the user lifts the front edge 101 and simultaneously drives the rotating part 60 to rotate upwards to a horizontal state; when the crank arm 30 is completely folded, the front edge 101 and the rear beam 102 are fixed by a fixing component to prevent the crank arm 30 from being unfolded accidentally.

As shown in fig. 8 and 9, the rotating member 60 is a rotating frame K, a rotating shaft X is provided in the base 20, an angle adjusting nail T is provided on the rotating frame K, a coupling center of the rotating frame K on the base 20 is offset from a coupling center of the rotating shaft X in the base 20, a front end of the angle adjusting nail T passes through the rotating shaft X in a threaded manner, an outer end of the angle adjusting nail T is located in a through hole K2 of a bottom plate K1 of the rotating frame K, and the rotating angle adjusting nail T can adjust a tilt angle of the rotating frame K and the base 20.

The angle adjusting nail T is threaded on the rotating shaft X, the front edge 101 is lifted up and down to drive the crank arm 30 to move up and down, and when the awning is adjusted to the required pitching position, the angle adjusting nail T is rotated to move inside and outside to a proper position to match different pitching angles of the awning. More specifically, when the angle adjusting nail T is rotated outwards, the angle adjusting nail T is matched with the awning of which the angle is adjusted downwards; when the angle adjusting nail T rotates inwards, the angle adjusting nail T can be matched with the awning with the upward angle adjusting function.

Preferably, the outer end of the angle adjusting nail T is a limiting end, the inner side of the upper end of the through hole K2 of the rotating frame K is correspondingly provided with a limiting block, and the limiting end and the limiting block are matched to form a limiting stress point so as to share the stress between the angle adjusting nail T and the threaded hole when the awning bends downwards. The angle adjusting nail T is connected with the through hole k2 in a threaded manner, and the effect is also to decompose the force applied to the angle adjusting nail T when the awning adjusts the angle downwards. Further enhancing the stability of the awning in the state of bending down.

As shown in fig. 5, the base 20 includes two coupling lugs 21, the rotation axis X transversely passes through the two coupling lugs 21, both side portions of the rotating frame K are coupled to the two coupling lugs 21 by shaft pins K3, and the shaft pins K3 are disposed in parallel with the rotation axis X. The axle pin k3 is parallel to the rotation axis X, but they do not rotate coaxially, i.e. the centers of the circles around which they rotate are offset from each other.

The side of the rotating frame K is provided with a first bearing seat 71 with a first vertical through hole 71a, the rear end of the crank arm 30 is provided with a second bearing seat 72 with a second vertical through hole 72a, and the first bearing seat 71 and the second bearing seat 72 are mutually coupled through a vertical pin 73.
